Built at the start of the 13C, this Romanesque church was extended up until the 16C in the Gothic style. The exterior is picturesque: a multiplicity of roofs and joins, a variety of building materials. Notice to the north the portal of the Virgin. In the building, see the 15C wrought iron chandelier and the copper baptismal fonts. The library (to the south of the ambulatory) has preserved its old appearance with low vaults and many columns.
